Perceptual processing techniques for video transcoding

a technology of video transcoding and processing techniques, applied in the field of video transcoding systems and methods, can solve the problems of reducing the output bit rate of video encoders, qps that may not provide the best possible qoe for transcoding video delivered to the end user, and reducing the qoe of encoded video, so as to improve the perceptual quality of transcoding video

Abstract

Systems and methods of video transcoding that employ perceptual processing techniques for enhancing the perceptual quality of transcoded video information, communications, entertainment, and other video content. Such systems and methods of video transcoding are operative to perform perceptual processing of an input video bitstream using predetermined information carried by the input bitstream. Having performed such perceptual processing of the input bitstream, the perceptual quality of transcoded video delivered to an end user is significantly improved.

Description

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] Not applicableSTATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

[0002] Not applicableFIELD OF THE INVENTION

[0003] The present application relates generally to systems and methods of video transcoding, and more specifically to systems and methods of video transcoding that employ perceptual processing techniques for enhancing the perceptual quality of transcoded video information, communications, entertainment, and other video content.BACKGROUND OF THE INVENTION

[0004] Systems and methods of video encoding are known that employ quantization techniques for reducing the bits from video encoders. Such video encoders frequently employ quantization with varying step-sizes that can have substantial effects on the output bit rates of the video encoders, and on the perceptual quality (also referred to herein as a / the “quality of experience” or “QoE”) of encoded video information, communications, entertainment, and other video content (also...
